(Non)retroflexivity of slavic affricates and its motivation : Evidence from polish and czech <č>
(2005)
The goal of this paper is two-fold. First, it revises the common assumption that the affricate <č> denotes /t͡ʃ/ for all Slavic languages. On the basis of experimental results it is shown that Slavic <č> stands for two sounds: /t͡ʃ/ as e.g. in Czech and /ʈʂ/ as in Polish.
The second goal of the paper is to show that this difference is not accidental but it is motivated by perceptual relations among sibilants. In Polish, /t͡ʃ/ changed to /ʈʂ/ thus lowering its sibilant tonality and creating a better perceptual distance to /tɕ/, whereas in Czech /t͡ʃ/ did not turn to /ʈʂ/, as the former displayed sufficient perceptual distance to the only affricate present in the inventory, namely, the alveolar /t͡s/. Finally, an analysis of Czech and Polish affricate inventories is offered.
In this paper, we present the Multiple Annotation approach, which solves two problems: the problem of annotating overlapping structures, and the problem that occurs when documents should be annotated according to different, possibly heterogeneous tag sets. This approach has many advantages: it is based on XML, the modeling of alternative annotations is possible, each level can be viewed separately, and new levels can be added at any time. The files can be regarded as an interrelated unit, with the text serving as the implicit link. Two representations of the information contained in the multiple files (one in Prolog and one in XML) are described. These representations serve as a base for several applications.
This paper presents the results of Open Quotient measurements in EGG signals of young (18 to 30 year old) and elderly (59 to 82 year old) male and female speakers. The paper further presents quantitative results on the relation between the OQ and the perception of a speaker's age. Higgins & Saxman (1991) found a decreased OQEGG with increasing age for females, whereas the OQEGG in sustained vowel material increased for males as the speakers age increased. In Linville (2002), however, the spectral amplitudes in the region of F0 (obtained by LTAS-measurements of read speech material) increased with increasing age independent of gender; this could be interpreted indirectly as an increasing OQ. We measured the OQEGG not only for sustained vowels, but also in vowels taken from isolated words. In order to analyse the relation between breathiness in terms of an increased OQ and the mean perceived age per stimulus a perception test was carried out in which listeners were asked to estimate speaker's age based on sustained /a/-vowel stimuli varying in vocal effort (soft - normal - loud) during production. The results indicated the following: (i) The decreased OQ for elderly females originally found by Higgins & Saxman is not apparent in our data for sustained /a/-vowels. For our female speakers no significant difference between the OQ of young and old speakers was found; for elderly males, however, we also found an increasing OQ with increasing age.(ii) In addition, a statistically significant increased OQEGG occurs for the group of the elderly males for the vowels from the word material. (iii) Our results show a strong positive relation between perceived age and OQ in male voices. Regarding (i) and (ii), at least the male speaker's voice becomes more breathy as age increases. Considering (iii), increased breathiness may contribute to the listener’s perception of increased age.
Elke Kasimir´s paper (in this volume) argues against employing the notion of Givenness in the explanation of accent assignment. I will claim that the arguments against Givenness put forward by Kasimir are inconclusive because they beg the question of the role of Givenness. It is concluded that, more generally, arguments against Givenness as a diagnostic for information structural partitions should not be accepted offhand, since the notion of Givenness of discourse referents is (a) theoretically simple, (b) readily observable and quantifiable, and (c) bears cognitive significance.
This paper describes the creation and preparation of TUSNELDA, a collection of corpus data built for linguistic research. This collection contains a number of linguistically annotated corpora which differ in various aspects such as language, text sorts / data types, encoded annotation levels, and linguistic theories underlying the annotation. The paper focuses on this variation on the one hand and the way how these heterogeneous data are integrated into one resource on the other hand.
We present a system for the linguistic exploration and analysis of lexical cohesion in English texts. Using an electronic thesaurus-like resource, Princeton WordNet, and the Brown Corpus of English, we have implemented a process of annotating text with lexical chains and a graphical user interface for inspection of the annotated text. We describe the system and report on some sample linguistic analyses carried out using the combined thesaurus-corpus resource.
[D]ie polnischen Familiennamen [unterlagen] bis ins 19. Jahrhundert hinein nur geringer amtlicher Kontrolle [...]. Diese Situation begünstigte den sukzessiven Aufbau onymischer Allomorphik aus den […] Flexions- und Derivationsmorphemen, die ursprünglich zur Bildung von Herkunftsbezeichnungen, Patronymika und Übernamen angewendet wurden. Die sekundäre Nutzung dieser Flexions- und Wortbildungsmorpheme als onymische Suffixe trieb den […] Dissoziationsprozess der Familiennamen voran. Die wachsende Produktivität dieser onymischen Morphe, die bis heute andauert, sicherte ihnen die Spitzenposition unter den Proprialitätsmarkern im polnischen Familiennamensystem. Heute sind die onymischen Allomorphe -ska, -ski, -icz, -ak das wichtigste Mittel, mit dem die Zugehörigkeit eines Wortes zum Onomastikon gekennzeichnet wird. […] In diesem Beitrag werden die Entstehungswege und die Ausbreitungspfade der drei produktivsten Gruppen der polnischen onymischen Suffixe präsentiert. Es werden auch die außersprachlichen Faktoren berücksichtigt, die die Erhöhung der Produktivität durch sukzessive Erweiterung der Kombinationsmöglichkeiten der einzelnen Suffixe ermöglicht haben. Es wird gezeigt, dass die ursprünglichen Selektionsbeschränkungen der Basen mit den Suffixen (Toponyme + -ska-Suffixe, Appellative und Adjektive + k-haltige Suffixe, Vornamen + -icz-Suffixe) im Zuge ihrer Ausbreitung und Festigung aufgegeben wurden. Die onymischen Allomorphe sind heute frei kombinierbar und können im Falle des Namenwechsels zur Bildung eines neuen Namens herangezogen werden.
This paper discusses the use of XSLT stylesheets as a filtering mechanism for refining the results of user queries on treebanks. The discussion is within the context of the TIGER treebank, the associated search engine and query language, but the general ideas can apply to any search engine for XML-encoded treebanks. It will be shown that important classes of linguistic phenomena can be accessed by applying relatively simple XSLT templates to the output of a query, effectively simulating the universal quantifier for a subset of the query language.
This paper describes the processing of MRI and CT images needed for developing a 3D linear articulatory model of velum. The 3D surface that defines each organ constitutive of the vocal and nasal tracts is extracted from MRI and CT images recorded on a subject uttering a corpus of artificially sustained French vowels and consonants. First, the 2D contours of the organs have been manually extracted from the corresponding images, expanded into 3D contours, and aligned in a common 3D coordinate system. Then, for each organ, a generic mesh has been chosen and fitted by elastic deformation to each of the 46 3D shapes of the corpus. This has finally resulted in a set of organ surfaces sampled with the same number of 3D vertices for each articulation, which is appropriate for Principal Component Analysis or linear decomposition. The analysis of these data has uncovered two main uncorrelated articulatory degrees of freedom for the velum's movement. The associated parameters are used to control the model. We have in particular investigated the question of a possible correlation between jaw / tongue and velum's movement and have not find more correlation than the one found in the corpus.
A fundamental question in the study of speech is about the invariance of the ultimate percepts, or features. The present paper gives an overview of the noninvariance problem and offers some hints towards a solution. Examination of various data on place and voicing perception suggests the following points. Features correspond to natural boundaries between sounds, which are included in the infant's predispositions for speech perception. Adult percepts arise from couplings and contextual interactions between features. Both couplings and interactions contribute to invariance. But this is at the expense of profound qualitative changes in perceptual boundaries implying that features are neither independently nor invariantly perceived. The question then is to understand the principles which guide feature couplings and interactions during perceptual development. The answer might reside in the fact that: (1) adult boundaries converge to a single point of the perceptual space, suggesting a context-free central reference; (2) this point corresponds to the neutral vocoïd, suggesting the reference is related to production; (3) at this point perceptual boundaries correspond to the natural ones, suggesting the reference is anchored in predispositions for feature perception. In sum, perceptual invariance seems to be grounded on a radial representation of the vocal tract around a singular point at which boundaries are context-fee, natural and coincide with the neutral vocoïd.
